The argument you're making has often been made as "there are different kinds of genius". The research seems to have debunked this. Rather than seeing multiple ways to be a genius, we see some general intelligence ability that helps you no matter what you're trying to do. In the case of our painter, if we're talking about Michaelangelo or something, he'd likely come out with an excellent IQ. As an aside, IQ tests don't try to make you do math problems and the like, it's all pattern matching kinds of questions where you learn all of the necessary context in the test itself. Which makes sense right, it's trying to measure your ability to learn and generalize, not what you happen to know before you take the test.
